•
Replace the fan filter every three months
•
Clean the air inlets once a week.
Cooling maintenance encompasses cleaning the fan module and cleaning the air
inlets on the front of the Acme Packet 4600 chassis. Cleaning the fan module
requires that you remove the module itself. If you are not shutting down the Acme
Packet 4600, this procedure must be performed quickly or else the system may
overheat and cause packet processing to stop.
This maintenance should be performed alongside other preventive maintenance to
take place within a planned maintenance or downtime window, during off-peak
hours.
To clean the fan module:
1. Remove the fan module from the chassis.
2. Spray compressed air into the fan module to dislodge and blow away any
contaminants and clean out the fans.
3. Replace the fan module.
To clean the perforated air inlets:
1. Remove the bezel from the chassis by gripping the two corners and pulling on
it. The bezel is held on magnetically.
